Hmm, that's borderline for me; I bet it's less in 1080p mode, but I'm concerned about alias/moire at that resolution. I'll have to wait and see some video and maybe even play with one before committing. It does look promising though.
Thanks for the info!

Several GH5 beta testers have stated that the camera is delivering the full 12 F-stops of V-log dynamic range, so it would appear that the GH5 has at least 1 F-stop of DR over the GH4. ( even though on paper they are supposed to be the same 12 F-stops )

I spoke with a Panasonic rep at CES and was told that the GH5 will ship without V-Log and it will still be a $100 extra - so factor that into the price if you are counting on using VLOG. When I asked why it is not included I was told "because it is essentially a consumer camera" and they didn't want to field a million questions from amateurs who were not able to work with log footage. I think that is lame.

Nick Driftwood, one of the GH5 beta testers has stated that the GH5 dynamic range is a big improvement over the dynamic range that the GH4 captures.

Here's a comment from Dan Chung ( filmmaker and editor of NewsShooter.com ) stating what Nick Driftwood said to him...

"Nick tells me he believes the Lumix GH5 definitely has big improvements over the GH4 in DR and even though 2 thirds of a stop is probably where its at, it definitely appeared perceptually to be around a stop better." : https://vimeo.com/198489956

Guys, this might be a dumb question, not sure since I'm relatively new to film making, but would love to get your advice on this:
I currently use EF and EF-S lenses on my GH4 with the Aputure Lens Regain adapter. But apparently there's no crop factor in 4K on the GH5.
So what effect would my current focal reducer have if fitted to the GH5? Will it work or should I just sell the Lens Regain and buy a MFT to EF adapter without focal reduction?

I think that's a big unknown right now, as I'm sure some SpeedBooster + lens combinations that worked for the GH4 won't work for the GH5 because the crop factor is now 2.0.

Veydra stopped working on their new anamorphic primes for the GH4 because they were told that GH5 anamorphic would be very different than GH4 anamorphic.

Hopefully Vedra will release their new anamorphic primes when the GH5 10-bit 4:2:2 400 Mbps anamorphic upgrade is released this Summer. ( it might even be a 5K format if it uses the full sensor ) Should be a killer combo.

Thanks Guy, I just had to go do more research as everything I had read or watched said it didn't have any crop factor at all.
Did find a clip on youtube specifying 2.0 crop over full frame. So does that mean a 50mm full frame lens becomes a 100mm?

Actually no. A Micro 4/3 sensor is roughly half the width and half the height of a Full Frame sensor, so to match the FOV ( field of view ) of a Full Frame lens you would use a lens that is half the focal length.

Actually Tony Northrup explains it perfectly and is the other way around as you say, a 200mm lens of a FF camera becomes 400 on the M4/3 (look at the sensor size comparing), a 24 mm on FF becomes 48 on M4/3 and so on.

If your Lens Regain works when you are shooting in 1080p mode on the GH4 it should have no problem working on the GH5 in 4K since they are effectively the same size area, despite being different sensors.

iPhonedo published a CES 2017 interview with a Panasonic rep. At around the 4:00 mark the Panasonic rep talks about the Summer firmware upgrade that will enable 400 Mbps 10-bit 4:2:2 FULL SENSOR anamorphic recording, which would be a 5K shooting mode. He also mentions non-anamorphic OPEN GATE 400 Mbps 10-bit 4:2:2 FULL SENSOR recording, where you do your 16:9 cropping in post from the FULL SENSOR recording : https://www.youtube.com/watch?v=IbGTmGReDdc
